В чём ошибка discord.py?

Ошибка:
Ignoring exception in command __balance:
Traceback (most recent call last):
File "C:\Users\TupaBan\AppData\Local\Programs\Python\Python38\lib\site-packages\discord\ext\commands\core.py", line 85, in wrapped
ret = await coro(*args, **kwargs)
File "ekonomika.py", line 47, in __balance
description = f"""Баланс пользователя **{ctx.author}** составляет **{cursor.execute("SELECT cash FROM users WHERE id = {}".format(ctx.author.id)).fetchone()[0]} :leaves:**"""
TypeError: 'NoneType' object is not subscriptable

The above exception was the direct cause of the following exception:
